1. A rechargeable battery comprising:
an electrode assembly wound with a separator between a first electrode and a second electrode and having a bottom side, a top side, and a lateral side extending between the bottom side and the top side;
an electrode tab extending from the lateral side of the electrode assembly;
a first exterior material including an opening receiving the electrode assembly;
a second exterior material covering the opening, and combined to the first exterior material to seal an internal side of the first exterior material; and
a reinforcing member having greater rigidity than the first exterior material and the second exterior material, disposed between the electrode assembly and the first exterior material, and including a side wall for surrounding the lateral side of the electrode assembly from which the electrode tab extends from the electrode assembly,
wherein the electrode tab is bent to extend around the reinforcing member to pass between the first exterior material and the second exterior material.
